OK - - package came in today USPS straight from Taipei. Another came from Portland about three weeks ago; but, alas, contained the wrong item. But it made a great opportunity for a little comparo.
Both 2009 models of the redesigned RST R1 dual crown: R-One Pro and R-One Super. Pro is very similar to previous R-1s with the addition of a Boxxer-compatible bolt pattern in the top crown for a direct-mount stem. R-1 Super gets Extreme Makeover Frok Edition with semi-open oil bath, rebound and compression damping and the Boxxer-compatible drilling.
R-One Pro (rebound damping only)
Rebound in the bottom
Will install the Super as soon as I can order my Sunline Boxxer direct-mount stem (that will get a set of Sunline 29er bars as long as I'm at it). Stems are out of stock at the moment. Then, if the snow ever subsides, I'll wring it out and post a ride report.
